I am sending my T-trim back to vortech to upgrade to Ti-trim. This is going on my 408 I have trick flow 20511r heads 10.5-1 gonna be on e85. Don't see to many combos using the Ti-trim. I have a 95 mustang so Im using 94/95 brackets. I know a YSI would be a better choice for a 408 but its what I have to work with.
